Application filed May 12,

This invention relates to improvements in intermittently operated mechanisms, and more particularly pertains to an improved form of changeable exhibitor employing a flexible web provided with illustrated or printed sections adapted to be successively displayed for advertising and other purposes.

ll hile this invention is here illustrated as embodied in a changeable enhibitor for ad vertising and similar purposes, it will be ob vious that it will not be limited to this adapta tion but finds a wide lield of utility for other purposes.

The principal objects and adventages which characterize this invention residein the provision of improved means for intermittently operating a sectionalized' web for exhibiting purposes; the provision of improved means. for moving a web for exhibiting and other purposes; the provision of improved. means for intermittently feeding a web and for reversing the direction of movement or" same; the provision of improved means for intermittently exhibiting a series of illustrations or printed matter on a continuous. flexible web; and the provision of improved means for intermittently feeding a printed or illustrated web and for reversing the web at the proper time. i

This invention further and more specifically relates to an electrically actuated, changeable exhibitor having a web wound from one reel to another and reversed automatically for bringing the advertising or other sections thereof successively into view at a display opening or window in the casing in which the parts are contained.

Among the more specific objects of my in vention are, first to improve the construction of devices of the kind mentioned; second, to provide an improved form of switch mechanism stopping the web at predetermined intervals to properly display the sections thereof. and third. to provide a slower rotat ng switch for automatically reversing the eg h such switch having SQCilOZlS'lD the reverse order so constructed that the web may be reversed at any desired pointin its length. say after certain number of sections have been displayed.

Gther and further objects of my invention will appear from the following description, taken in connection with the accompanying drawings, in whi-ch Figure l is a front view of a changeable Fig. 14 is a view of tion oi? the web at predetermined points 1922. Serial No. 560,410.

Fig. 27 shows in perspective view interactdevices between the clutch operating mechanisms shown in Fig. 20.

The driving mechanism shown, in Figs. 1

and ,2, includes an electric motor 10 having on its armatur'e'shaft 11, a worm 12 in mesh with a worm gear 13 fixed on a shaft 14 j ournaled in hangers, 15, 15, on a plate 16 secured to one of the brackets 2 by screws 17 as either reel is clutched to its spindle it will be the winding reel.

The clutch mechanism for each reel consists of a sleeve 21 loosely and shdably mount- I ed on the associated live spindle 9 and having a groove 22 engaged by the forked end of a yoke 23 secured to a shift rod 24. Fixed to the spindle 9 is a ratchet wheel 25 engaged by a pawl 26 pivoted on the end of the reel 3, as shown in Fig. 8. A spring 27, carried by the reel 3, acts to force the pawl into engagement with the ratchet wheel 25 for connecting the reel and spindle 9. To raise the pawl 26 out of engagement with the ratchet wheel 25 to disconnect the reel from its spindle 9', the sleeve 21 is provided with a radial flange 28, which when moved under the end 29 of the pawl raises and holds it out of engagement with said ratchet wheel.

' For operating each clutch device are two alined solenoids 30, 31, as shown in Figs. 1, 12 and 13. These solenoids are held in place by clips 32 on a base plate 33 secured to the back 1 as shown. The core or armature 34 is in the form of a rod, as shown in Figure 13, and is connected at one end with the shift rod 24. When one solenoid is energized the other is deenergizcd, and when the one 31. is energized the rod 34 is moved in direction of arrow 31 to operate the clutch and disconnect the reel from its spindle 9. When the other solenoid is energized, the rod 34 is moved in the opposite direction, arrows 30, and connects the reel with its spindle 9. This is done automatically at predetermined intervals for stopping the web after a display section has been brought to View at the window and allow the web to remain stationary for a length of time to display such section.

Journaled in the plate 16 is a vertical shaft 35 having at its lower end a worm wheel 36 in mesh with a worm 37 on the shaft 14, as shown in Figs. 1, 3 and 4. Fixed on (his shaft adjacent its upper end is a rotary switch member 38, made of insulating material and upon which bear a plurality of spring controlled contact fingers or brushes 39, 40

and ll, each pivoted on a binding post 12 secured to'the plate 16. The switch member 38 has an annular commutator ring 43, against which the finger 39 bears, while the finger e0 bears against the surface of said member This surface is raised at one point in its cirthe 'middle cumference and thus makes the member somewhat cam-shaped, as shown in Figs. ll and 18. The finger 4L1 bears against a ring e5 interrupte'd at the cam projection, as shown in Fig. 18. This provides a gap d5 bridged by the insulating material of which the I11G111" ber 38 is made and breaks the circuit through finger l1, in the manner to be presently do scribed. bar 46 set in the member and in contact with the of the. ring 45, as shown in -,14l, 1? and 18. This bar is connected with the outer ring 43 by a conductor strip 45,".

Toreverse the direction of the web 4,1 provide another rotary switch member 48 of insulating materiahsecured to a gear At this cam projection there is a wheel 49in mesh with a worm 50 on the shaft 35, as shown in Figs. 1 and 4:. Pivoted on the plate 16 is a plurality. of spring controlled segments of each set have the same peripheral length, are-also spaced apart CiIOLHlTfElQD? tially or endwise a distance slightly greater 7 than the length of a blade, so that there is a blade of oneset opposite the space between blades in the other set, as shown in 16.

Thus the brush'52, while being wide enough to be in the path of movement of both sets of blades, will only contact with one at a time, one moving out of contact just before the following one of the other set moves in. The r segments 56 of one set engage the ring 5st, while the segments 57 of the other engage the ring 55, there being a portion of the member 48 between the two sets to insulate them from each other. The path of the current, when brush 52is in contact with one segment, is through such parts and the associated ring and, not through the other ring and its segments; thus when the finger 52 is in contact with one of the segments 56, the web will be moved in one direction, but when in contact with one of the other segments 57 the web will move in the opposite direction. The peripheral length of the segment proportionate to the length of the web or the number of successive sections into which the web is divided, and the rate of rot on of the switch member i3 is slower than the other switch member 38 "d is such that t n the brush 52 stays in contact with one segment or blade until all of the display sections for that seg thus reversing the web, and allowing the web to run in the opposite direction to the siine extent betore being reverseclag: n. cycle of operations repeats, as long as the motor is rotated the web reversct aiter a display or its sections. 1

anC

This reversing mocha iism may be set to reverse the web at any predetermined point in its lengtl that is, it the full length of the web is divided into a given number of display sections, the web may be reversed at the end of the display of all or thosesections, by putting on switch member 18 having segments of the length to accomplish this, this member -8 being clamped to the gear wheel 49 by a not or like part 58 Should it be desir d o exhibit a number of those section the first mentioned member would be placed by one with segments or 1 l s ing a peripheral length for the Current is supplied by a {a battery 59, as shown in 1, and from which leads a wire 60 coninzcted to he brush 39. The other wire 61 leads to magnet 31 ot the lower reel 3. A vire 62 connects wire 61 with the magnet 30 of the upper reel. A wire 63 leads from the magnet 30 of the lower reel to the linger 51. in wire 6 connects the linger 53 vith the magnet 30 of the upper reel. A wire 65 connects the magnet 30 of the lower reel with wire 62.

mic motor 10 is connected to the wires 60 and 61 by wires 6'? and 66, respectively.

Bearing against the lower guide rollerG is a contact finger mounted as shown in Figs. 9 and 11 on a crossbar 69 w rich extends etween the brachets'Q, This finger 68 is constantly 'n C11tttCiQ with the roller 6, this being live s t s the circuit of the device.

With. reference tol 19 to 23 inclusive it *ill be obs-ierved that certain elements of the in vcntion. heroinbetore lcscribed, l. Referring to'liig 's. and 20, ided a base 85 which is provided iames 86 and 8 said frame (3K) ed with bearine's and 90, said rotatable live 7 shafts having}; I. fixedly mo nted hereon, re-

' ars being in mesh. (l ne is operatively in mesh wit 1 inion 96, which latter is fixedly secured to the inner end of the shaft 91, said As best seen in 20, each of shafts 92 and 98 has a ratchet wheel 100and101, respectively, fixed to the shafts and in proximity to the inner tapered ends 01' the shaft,

the teeth of said wheels beingopposite. The rollers 97 and 98 are provided with spring pressed pawls 102 and 103, respectively, said pawls having lingers 10 1 and 105 for engagement with the annular flanges 106and 107 provided on. clutch members 108 and 109 respectively. The clutch members are mountli'reely and and are actuated at the proper instant releasing or en a in one or the other c; b L: n

for 7 oi the pawls 102 and 103. v

The actuating mechanism for the clutch members comprises the arms 110 and 111, secured fixedly to the inner ends of the rods 112 and 113, respectively, which latter pass each through one of the solenoids 114 and 115, constructed as Wlll presently be described. The free ends of the arms 110 and.

111 he in annular grooves in said clutch mem. bers 108 and 109 respectively. For the sake of convenience the solenoids are mounted on an extension 116 of the base and are each provided with double windings, designated A-IA and BB, respectively.

he shaft 91 has a worm gear 117 fixedly secured thereto and meshing with a worm 1'18 fixedly secured to the armature shaft 119 of the electric motor 120, which latter 1s secured.

to the side frame 86 by bolts 121 or the like.

The shaft 91 is also provided with a worm 1 22 fixed to the medial portion of said shaft, said worm meshing with a worm gear 123 fixedly secured to one end of the timer s'v'vitch shaft 124;, which latter shaft is longitudinally arranged and rotatably mounteo in. bearings 125125 on the plate 88. Near the medial portion of the shaft 12st there is fixedly mounted thereon. a worm 126, which latter operatively meshes with a worm gear 127, said gear being rotatively mounted on a stud 128 which projects from the plate 88, said gear 127 operating theireversing switch, orally designated 129. Also fixedly mounted upon the shaft 1241, is a switch drum 180, preferably insulating material. The switch 129 regulates the time of reversal of the drums or rollers which feed the web and the drum 130, wlth 1ts connections, controls the slidably on the shafts 92 and genintermittent feeding of the web, that is, it controls the energization of the windings A and B of the electro-magnets or solenoids, 114 and 115. i

The feed rollers 97 and 98 are relatively close together, the web being trained over idling rollers 131 and 132 mountedon rods near the ends of and extending between the frames 36 and 87, the portion or the web 99 between the rollers 131132 being the exposed portion. This exposedportion of the web is guided by the yieldingly mounted channels 134 and 135, said channels being fixed to tubes 136-436, said tubes being slidably mounted upon transversely arranged rods 137-137 which latter are mounted in s the side framds 86 and 87. Helical springs 133-138 surround the rods 137 and abut the tubes, the tit 'es in turn being limited in movement away from the side frames by collars 139 mountedon said rods. Aglass plate 140 is arranged above the web in demountable channels 141141, secured to the frame 86 and 87.

The switch drum 130 is provided with two grooved rings 142 and 143, in which the ends of resilient contact arms 144 and 145 seat, said arms being fixedly mountedin insulatedbinding posts on the plate 88. The drum 130 itself is provided with a groove 146 in'whic-h one end of the resilient contact arm 147 seats, saio arm being. fixedly mounted on the plate 88 in an insulated binding post 148. At a proper point in thegroove 146 is provided a r me allic pin 149, connected to the ring 14-2,

(Fig. 25). The ring 143 extends but part way around the drum. The rings 142 and 143 are mounted on the drum 130, so they touch each other and are thus electrically connected,

the construction ofthe drum 130 and the parts carried thereby, being more clearly shown in Fig, 26. The rings 142 and 143 and the pm 149 correspond respectively to the rings and 4-5 and the bar 46 above described connection with the switch member 38, the

relation of the parts to the lingers and arms bearing thereon, being substantially the same in each case and for the same purpose, the principal difference being that contact between the contact arm 147 and the pin 146 is not momentary as above described for contact between the finger 40 and the bar 46, other neans being provided as described below, for at once opening the circuit so closed by the arm 147.

The reversing switch 129,. comprises a core 156 of insulating material, fixedly secured to the worm gear 127 and supporting a pair of spaced grooved metallic disks or rings 151 and 152, (Fig. 24) said rings being, respectively, connected with the spaced insulated timing disks 153 and 154-. The disks 153 and 154 are provided each with radial contact heads 155 and 156, respectively arranged so that the heads are relatively alternately disposed asseen in Fig. 20. A resilient contact finger 157 isin the path of movement of the heads 155 and 156 and is fixedly secured to the binding post 148. Resilient contact fingers 158 and 159 are mounted on insulated binding posts on the plate 88, said fingers lying in the grooved rings 151 and 152, respectively. i

As best shown in-Figs. 22 and 23, the solenoids 114 and 115 are secured to the base portion 116, a block 160 provided with socket-s 161161 servingtoseat said solenoids, and a clamp 162, secured to the block 160 engages said solenoids and prevents their displacement. i

The rods 112 and 113, which are in part the movable cores of the solenoids, are extended through the solenoids and their projecting ends serve as circuit controlling means. To this end the rods are provided with non-metallic insulating portions 163, in which are supported metallic rings 164, 165, 166, 167, 168 and 169. The rods pass through insulating blocks 17 O and 171, and pairs of spring fingers 17 2-173, and 174175, respectively, are supported by said blocksand project therefrom for contact with said metallic rings. Thefingers 172 and 174 are relatively shorter than those designated 173 and 175 for a purpose which will presently appear.

Of the rings 164, and 166 carried the insulation 163 on the rod 113,-the rings 164. and 165 are contact rings,the ring 166 being employed solely to hold the assembly of contact rings in place; similarly, of the rings 167, 168 and'169, only the rings 167 and 168 are contact-rings and the ri'ng1-69 serves solely as a retaining ring.

The mechanical construction 'isfsuch, that when the rod 113 is in its extreme right hand position, as shown in Fig. 22, the ring 164 is between and electrically connects springs 172,

and the ring 165 is between the springs 172 and173 and is not in contact with any of said springs, the springs 173 being then resting upon and separated by the insulation 163; also, that when the rod 113-is in its extreme left hand position, the ring 165 is between and connects the springs 173, the ring 164 is between the two pair of springsand not in contact with any of them, the springs 17 2 at that time resting upon and being separated by the insulation 163. Similarly, the rod 112'in its left hand position connects the springs 175 by the ring 168, and in its right handposition connects the springs 174 by the ring 167, and for either of said positions, the said springs not so connected, rest upon the insulation carried bythe rod and are electrically separated thereby.

As best seen in Figure 20, current is supplied by-the conductors 176177, the latter extending to abinding post 178, whence a conductor 179'leads, through a resistance coil 180, to one side of the electric motor 126,

thence a conductor 181 leads from the other side of the motor to a binding post 182, which latter carries the spring finger 144 and is connected to the conductor 17 (3. Thus the motor circuit is completed.

Each otthe solenoid windings is connectec by a common conductor- 188 to the binding post 178, the othersidesot said windings being connected by conductors 184, 185, 186 and 187 respectively to one of each pair of the resilient contact lingers 172, 17,3, 174 and 175. The other fingers 172 and 174, are connected respectively by conductors 188 and 189,'to the spring arms 158 and 159, and the other fingers 173 and 175, are connected. together by a conductor 190. The spring linger 145 is connected by a conductor 191 to an insulated brush 1 2, which is adapted to contact continuously with the guide roller 131, an insulated pivoted arm 193 being arranged to intermittently contact with said roller 181 through one each of a series of spaced openings 194 in the web, as the same passes over the guide rollers. A conductor 195 connects the arm 198 to the conductor 190.

In operation, assuming the parts to be as shown in Fig. 20, and currentis supplied to the conductors 17.6177, the timer shatt is rotated in the direction of the arrow A, the motor continuously operating. In the position of the parts as shown, the clutch element 108 is out, that is, the pawl 102 is engaging the ratchet 100 and the roller 97 isbeing operated. When the opening 194 between sections of the web permits the arm 193 to contact with the roller 131, current flows from the binding post182 through arm 144 and ring 142 to ring 148, springarm 145, conductor 191, arm 192, roller 131, arm 193, conductor 195 to conductor 190, thence through ring 168 on rod 112 to winding A4 thus moving clutch member 108 to raise pawl 102 and release roller 97, thus stopping the web. This movement ofthe'rod 112, moves the ring 168 from contact with the springs 175 and brings the insulation 163 between them, thus deenergizing the winding A, and at the s ne time brings the ring 167 between and in contact with the springs 174 to close the circuit of thewinding A at this pointand place it in condition for complete closure by the switch member 180. After a desired interval of rest of the web 99, or display interval, during which the shaft 124 and the switch member 130 are continuously in motion, the pin 149 engages-arm 147, and current flows through conductor arm 157 dish 154, arm 159, conductor 189, springs 174 andring 167 to winding A, thereby Withdrawing clutch 108 and permitting roller 97 to be again rotated. WVhen the web, by a series of steps, reaches one end of its run, the disk 154 has been rotated to bring the tooth 156 thereof clear of the arm 157, the latter being immediately thereat'ter'engaged byone of the teeth 155 of arm 147, arms 157, 158, and'conductor188,

springs 172, ring 164 to winding B. The rod I 113 is in the position shown in Fig. 22 when the reversal takes place, and upon energizetion of the windinn B said rod is moved to release pawl 102-3 to engage ratchet 101 starting roller 98. Said movement ofthe rod 113 actuates rod 112 to move pawl 102out of'engagement with its ratchet 100 by means 011217 lever 196 1irotcd at 197 tothe base 85, said lever engaoing pins 198199 extending from the hubs or the arms 110 and 111, respectively as shown in Fig. 27. A bracket 200iis fixed to the pivot 197 and a coiled spring 201 is connected to saio bracket and the lever 196 tending to hold said lever in either position to which it is moved. The operation continues as previously described until the web reaches the end of its travel whereupon itis again reversed. I

From the above description it will appear that the operation and result of the construction shown in Figs. 19 to 27, is much the same as for the construction shown in Figs. 1 to 18, the principal diiiorences being, first, that with the construction of Figs. 19 to 27, each solenoid winding has included in its energia ing circuit a contact ring carried by the rod moved by the action of said winding, and contact springs engaging said ring, thus insuring that each winding shall be energized'tor a sufiicient interval to effect movement of its rod, and further insuring the breaking of the energizing circuit in each case, as a. result of the action of the winding; and second, that invention, it to be oi course understood that the det 11S 01? construction and arrangement of parts may be variously changed and modified without departing from the spirit and scope of my invention.
